The terrific Enough Said begins with the loose, sunny charm of a rom-com. Masseuse Julia Louis-Dreyfus, tiny as a sparrow, falls for an ador- able lug (the late, great James Gandolfini). The lovers have both chemistry and camaraderie. But writer-director Nicole Holofcener tugs them toward a confrontation that snaps like a trap. Rom-com gives way to sharp, intimate truth.
